admirable means of effecting our purpose, especially where the patient suffers from more than the usual opiate torpidity of the liver. We shall have room enough if not for an extended ride at least for a mile track around the Island, and a stud, however unlikely to set John Hunter looking to his laurels, capable of affording choice between a trotter and a cantering animal. During the summer there will be ample opportunity for those who love horticulture to take exercise in the flower and vegetable garden attached to the institution, and such as wished might be assigned little plots of ground whose management and produce should exclusively belong to them. Looking for a moment from the therapeutics to the economics of the matter, I can see no reason why the house might not rely largely upon itself for at least its summer vegetables and its fruit--if the poorer patients were permitted to pay part of their dues, when they so elected and the exertion was not too much for them, by taking care of the grounds. Another admirable means of exercise will be found in rowing. Our Island must have a good substantial boat-house, containing a good-sized barge for excursions and several pleasure-boats pulling two or three pair of sculls each; perhaps, eventually, a pair of racing-boats for such of our guests as were well enough to manage a club. Bath-houses for the convenience of those who love a plunge or a swim will be indispensable--affording facilities for a species of summer exercise which nothing can replace. In winter and summer the bath must be our principal reliance for promoting that vigorous action of the excretory system which with healthy nutrition is our great aim in treating the patient.
